Abstract

  • 1.

    1. Total lipid was extracted from chicken (Gallus domesticus) epidermis, leg scale, claws, feathers and preen glands and analyzed by quantitative thin-layer chromatography.

  • 2.

    2. All of the tissue lipids contained large proportions of wax diesters, triglycerides, and free sterols and variable proportions of phospholipids, steryl esters and free fatty acids.

  • 3.

    3. All of the keratinized tissues, but not the preen gland, contained ceramides, acylceramides and cholesteryl sulfate.

  • 4.

    4. Acylglucosylceramides were found only in full thickness epidermis.

  • 5.

    5. Glucosylsterols and acylglucosylsterols were found in the keratinized tissues, and may be of significance in the evolutionary history of the epidermal water barrier.

    Citation Excerpt :

    The possible benefits of a high LCP intake by preterm infants have been demonstrated in trials [78,79,89], but no studies have been performed with higher milk MUFA and lower milk LA and MCSAFA contents. Any lowering of the LA and MCSAFA intakes must on the other hand be weighed against the building of the skin's water barrier by LA [90–94] and the ease by which MCSAFA carrying TG are hydrolyzed in the gastrointestinal tract [95]. To arrive at a balanced catch-up growth of preterm infants it is necessary to know which ‘windows of opportunity’ are still open and which are definitely closed.
